Newcon Optik NVS 7-2 HDX Night Vision Biocular

The NVS 7-2 HDX from Newcon is a night vision biocular - its optical design incorporates two oculars, one objective, and a single intensifier tube. Dual-eye viewing provides comfort during extended viewing periods, while enhancing the level of depth perception within the scene. This low-light optic is configured with a high-performance system that features a high-quality second generation HDX intensifier tube that delivers a remarkable 54-57 lp/mm of resolution

The NVS 7 can be used hand-held, or fitted to a head or helmet mount for hands-free operation. Both oculars are fitted with a soft rubber eye cup; this provides moderate protection against bumps, and it also minimizes the amount of light that can reflect onto the operators face. This NVS 7 also features in-view low-battery and IR-on indicators.

There are many variables that affect the distance that one can see with a night vision device; the object's size, ambient weather and lighting conditions, the level of detail needed for recognition, etc. The important factors to consider when evaluating any night vision device are the generation of the intensifier tube along with its specified resolution and s/n ratio. The magnification, clarity, and light transmission performance of the NVD's optics also contribute to its low/no-light performance capabilities.

All NVDs sold by B&H feature bright-light protection systems. However, this does not mean that bright light can/will not damage the device. Exposure to bright light compromises the longevity and performance of image intensifier tubes.
